If the majority of offsprings exhibit a dominant character, then the parents must be:

Options

A. Both hybrids
B. One dominant and one recessive
C. Both recessive
D. Both dominant

Answer

To solve the question, "If the majority of offspring exhibit a dominant character, then the parents must be:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dominant and Recessive Traits**:
- In genetics, dominant traits are represented by capital letters (e.g., "I" for a dominant trait) and recessive traits by lowercase letters (e.g., "i" for a recessive trait).

2. **Analyzing the Offspring**:
- The question states that the majority of offspring exhibit a dominant character. This implies that more than 50% of the offspring show the dominant trait.

3. **Considering Parental Genotypes**:
- If both parents were homozygous dominant (e.g., "II"), all offspring would also be dominant (100% dominant).
- If one parent is homozygous recessive (e.g., "ii") and the other is homozygous dominant (e.g., "II"), all offspring would also be dominant (100% dominant).
- If one parent is heterozygous (e.g., "Ii") and the other is homozygous recessive (e.g., "ii"), the offspring would be 50% dominant and 50% recessive.

4. **Identifying Hybrid Parents**:
- The only scenario where the majority of offspring can exhibit a dominant trait, but not all, is when both parents are heterozygous (e.g., "Ii" x "Ii").
- In this case, the expected offspring ratio would be:
- 25% homozygous dominant (II)
- 50% heterozygous (Ii)
- 25% homozygous recessive (ii)
- This results in 75% of the offspring showing the dominant trait (both II and Ii), which fits the condition of the majority exhibiting a dominant character.

5. **Conclusion**:
- Therefore, if the majority of offspring exhibit a dominant character, the parents must be hybrid (heterozygous).

### Final Answer:
The parents must be hybrid (heterozygous).
